Application August14, 1946, Serial No. 690,502

the methods for extruding aluminum to any desired shape has becomepopular, such windows have increased in popularity, due to the fact thatthe window sash and window frame constructed in accordance with thelatest methods, are highly ernamental and are of such uniformconstruction that the windows constructed with them are highlysatisfactory.

With the ordinary casement window, the window sash containing the glassis hinged so as to teen and close like an ordinary door.

It is an object of this invention to produce a window sash and a windowframe construction that, in addition to being of a very neat appearanceand containing the minimum amount of metal for the required strength,are also so constructed that a Weather strip can be readily provided soas to effect a weather proof seal between the frame and the sash.

Another object of the invention is to produce a window frame bar that issubstantially a duplicate of the window sash and which is of suchconstruction that it can readily be built into a brick wall and formwith the latter a wind proof seal.

The above and other objects that may become apparent as this descriptionproceeds are at tained by means of a construction and an arrangement ofparts that will now be described in detail, and for this purposereference will be had to the accompanying drawing in which the inventionhas been illustrated in its preferred form, and in which:

Figure 1 is a section through a window frame and sash showing the partsin closed position;

Figure 2 is a top plan view of one corner;

Figure 3 is a section taken on line 3-3, Figure 2; and

Figure 4 is a fragmentary section to a scale substantially twice thatemployed in Figures 1 and 3 and shows with greater detail the weatherstrip and its relation to the other parts.

In the drawing reference numerals l and II designate the inner and outercourse of bricks, respectively, in a vertical wall. Reference numeral l2designates a pane of glass that is secured to the window sash by meansof putty l3. The invention to which this application relates 2 Claims.(CL 189L65) has reference to the shape and construction of the windowsash and window frame, which will now "be described in detail. Thewindow sash is 'of substantially Z-shape and has a vertical web I4provided at its upper edge with an outwardly extending flange l5 and atits lower edge with a flange 16 that extends in the opposite directionfrom flange l5 and terminates in an upwardly extending rib ll. Flange l5overhangs the outer wall of web l4 so as to form a rib l8 against whichthe putty can be positioned. The window pane rests on the upper edge ofrib I! and is held mpieee by the putty in the usual manner, The undersurface of flange [5 is provided with two parallel ribs l9 that arespaced apart and have their inner walls upwardly flaring when viewed asin Figure 1. The weather-strip 20 is positioned between ribs IS in themanner shown more clearly in Figure 4. The window frame is ofsubstantially the'same shape and size as the window sash and with theexception of the part positioned below line 2| in Figure 1, the two members are identical in shape and size. Instead of a short rib like thatdesignated by reference numeral H, the window frame has a wide web 22that'terrninate's in an outwardly extending flange 23 which projectsinto the space between adjacent brick courses. The window frame has avertical web Ma, a wide flange Hill and spaced parallel ribs l9a. Theupper flange Ilia corresponds to flange [6 of the window sash.

Referring now more particularly to Figure 4, it will be seen that thetwo ribs l9 have their inner surfaces downwardly flaring so as to forma. dovetail slot. Positioned in this slot is a weather strip formed fromspring metal and bent into the shape of a V. The weather strip is ofsuch size that when it lies in the dovetail groove with one side againstthe bottom, it is held in there quite firmly because the width is soselected that it can be snapped into position and will remain until itis removed by means of a suitable tool. The free side, which is at thetop in Figure 4, and which has been designed by reference numeral 24,normally extends over the tops of the ribs [9, as shown most clearly inFigure 3. When the window sash is closed, the weather strips. both atthe top and the bottom, when viewed as in Figure 1, are deformed so asto permit the edges of the ribs to come into very close engagement withthe opposed surfaces. The parts may be so adjusted that there is directcontact between ribs l9 and the opposed surfaces, but it is preferableif a short space is left as the sealing is taken care of by the weatherstrip and not by angular relation as shown in Figure 2.

ance when made from aluminum or aluminum alloy.

Window frames and window sash made of metal are usually mitered at thecorners and then welded by a flash welding process. This processnecessitates the forceable compression of the opposed edges and thisleaves an unsightly ridge along the weld. With the present construction,the ends are cut at the desired angle by means of a suitable metal sawand they are then adjusted into closed contact and right Instead ofwelding an angle iron like that designated by reference numeral 25 isriveted to flanges i4 and Ma in the manner shown in Figure 3 and thisangle is also secured to flanges I5 by rivets 26. When a joint isconstructed in the manner just described, care being taken to keep themitered edges in close contact, the joint between the two parts of theframe is almost invisible and the surface along the joint is smooth.

Particular attention is directed to the weather seal and to the mannerin which it is secured in position between the ribs 19 and in thedovetail groove thus formed. This form of weather :strip can be usedwith the construction of sash and, if not too thick, will adaptthemselves to irregularities in the opposing surfaces. Since the framemembers are extruded, the surfaces are, however, very smooth and as aresult the, seal is very effective at all points.

Having described the invention what is claimed as new is:

1. An elongated structural bar for use in making window frames having, aweb, a first flange projecting laterally from the web along one edgethereof, a second flange projecting laterally from the other edge of theweb and in a direction opposite to the first flange to form asubstantially Z-shaped cross section, a third flange projecting from thefree edge of said first flange in a direction towards said second flangeand parallel to said web, the width of said third flange being less thanthe width of the web, and a fourth flange projecting laterally from theedge of said third flange in the same direction as the first flange andparallel thereto, said fourth flange forming means for effecting aconnection with the building wall.

2. An elongated structural bar in accordance with claim 1 in which thesurface of said second flange that faces towards the plane of the firstflange, is provided with two parallel spaced ribs adapted to position aresilient seal element.
